The Physicist Who’s Challenging the Quantum Orthodoxy
For decades, physicists have struggled to develop a quantum theory of gravity. But what if gravity — and space-time — are fundamentally classical?
A New Map of the Universe, Painted With Cosmic Neutrinos
Physicists finally know where at least some of these high-energy particles come from, which helps make the neutrinos useful for exploring fundamental physics.
An Enormous Gravity ‘Hum’ Moves Through the Universe
Astronomers have found a background din of exceptionally long-wavelength gravitational waves pervading the cosmos.
What Can Jellyfish Teach Us About Fluid Dynamics?
Jellyfish and other aquatic creatures embody solutions to diverse problems in engineering, medicine and mathematics. John Dabiri, a fluid dynamics expert, talks with Steven Strogatz about what jellyfish can teach us about going with the flow.
The Simple Geometry That Predicts Molecular Mosaics
By treating molecules as geometric tessellations, scientists devised a new way to forecast how 2D materials might self-assemble.
A New Experiment Casts Doubt on the Leading Theory of the Nucleus
By measuring inflated helium nuclei, physicists have challenged our best understanding of the force that binds protons and neutrons.
An Explorer of Abyssal Depths Looks to Oceans on Other Worlds
The marine geochemist Chris German brings decades of experience studying seafloor hydrothermal vents to NASA’s preparations for visits to other ocean worlds in our solar system.
